My half is next weekend, and I'm traveling this weekend. Unlikely to be able to run due to some crazy last-minute schedule changes. I'm assuming that there's no point in trying to "make up" for the missed mileage, but I wonder what the impact might be on my race. I could see having more rest as being potentially beneficial as long as I get some easy runs in during the coming week.
I agree with jbarwick - I don't think a few extra days of rest will be detrimental, especially this close to the actual event.
